CAR ROOF.

Application filed February 19, 1921, Serial No. 445,253.

To all whom t may concern:

Be it known that l, illumini; lfl. SLA'r'rnN, a citizen of the United States of America, and a resident of Chicago, inthe county of Cook, State of illinois, have invented certain new and useful improvements in Car Roofs, ofwhich the following is a specication.

This invention relates to metal clad car roofs of the type which constitutes the subject matter of Letters Fatent No. 1,323,638, issued to me March 2, 1920, and this impiovement has for its obj ect v To provide a structural formation and combination of the sectional members composing the outer sheet n'ietal covering of the car roof, adapted to provide an approximately level nature to the exposed surface of the covering and prevent leakage of rain, etc., to the car interior at the juncture points of the sectional members, all as will hereinafter more fully appear.

ln the accompanying drawing Fig. l, is a transverse section, line l-l Fig. 3 of a car roof embodying` the invention.

Fig. 2, is an enlarged detail section on line 2 2 Fig. 3 showing the construction at the eave portion of the roof.

Fig. 3, is an enlarged detail longitudinal. section on line 3-3 Fig. l.

line l-i Fig. l, is a similar view on Fig. l.

Like reference numerals indicate like parts in the several views.

Referring to the drawing, l designates the usual side rails or plates connected by trans verse carlines 2, and carrying the eave rails or fascia boards 3, the ridge pole e, the purlins 5 and the wood sheeting or sub-roof 6, with the parts having the usual arrangement and connection in general use in railway freight cars roofs.

7 designates a plurality of sheet metal portions or members, which in connection with a plurality of intermediate channel plates 8 constitute the outer roof covering which overlies the sub-roof 6 above referred to, said portions being preferably of the sectional central and twin side plate formation described in detail in Letters Patent aforesaid.

In the present construction the channel plates 8 occupy transverse gaps in the subroof 6, with the upper ends of the vertical upturned webs of the channel plates disposed on a plane approximately the same Serial No. 538,704.

ztenewer. February 23,7`822.

9 designates downturned right-angle flanges on the respective sides of the sheet metal porti` is 7 and adapted for bearing Contact inst the respective inner faces of the upturned webs of the channel plates 8, as shown more particularly in Fig. 3.

l0 designates uptnrned flanges forming vertical and integral extensions of the aforesaid flanges 9 and ai oged in spaced relation therewith so as to form narrow channels for the reception of the downturned 'fianges of the cap pieces now to be described.

ll designates cap pieces of a channel shape in cross-section and having downturned right angle flanges at the sides adapted to enter and fit the above described channels formed by the soaced flanges 9 and l0 of the sheet metal portions 7, with the top webs of the cap pieces on a plane approximately even with that of the portions 7 and with said top webs resting upon the upper ends of the lianges l0 as shown.

l2 designates downturned flanges onI the outer e of the cap piece l1 for attachment to the fascia boards 3, and formed with orilices 13 adapted to register with the cavities of the channel plates 9 to permit a free outiiow of any water which may enter into said cavities. y

ln the present construction the respective ends of the cap pieces 1l will end ,at and engage 'the sides of the saddle blocks 14 of the running board l5 of the car roof, and the sheet metal portions 7 adjacent to said saddle blocks will have their flanges l0 removed and their flanges 9 formed to iit the metal conlining plates 16 of the aforesaid saddle blocks as shown in'Fig. et.

The present construction is adapted to meet in` an effective and economical manner, the requirement of flexibility in the roof corresponding with the flexibility of the car body structure and at the same time afford a rain tight connection between the sections and parts comprising the metal roof covering.

Having thns fully described my invention what l claim as new and desire to secure by Letters Fatent, is

l. In a car roof, the combination of a plurality of transversely arranged channel memthe channel members,

bers disposed in gaps of the sub-roof and having upstanding flanges, a plurality of transversely extending sheet metal sections having doivnturned marginal flanges adapted to Contact With the upstandin@ flanges of said dovvnturned flanges having vertical extension flanges in spaced relationto provide narrow receiving channels, and cap pieces ofa channel shape and` having downturned ianges adapted to fitthe channels formed by the aforesaid flanges.

2. In a ear roof, the combination of a plurality ,of transversely arranged channel members disposed in gapsof the 'sub-roof and having iipstanding anges, a plurality of transversely extendingsheet metal sections having doWnturned marginal flanges adapted to Contact with Y, the upstanding flanges of the channel members, said downtiirned fianges having vertical extension flanges in spaced relation to provide fnarrow receiving channels, and cap pieces of a channel shape and having down-turned flanges adapted to lit the channels formed bythe aforesaid flanges, saidcap pieces having at their outer ends downturned attach# ing yflanges formed with orilices adapted to register with vthe cavities of the channel members aforesaid.
